SEAL-LOCK.

SPECIPICATIQN forming part of Letters Patent No. 363,371, dated May 24-,.1887.

Application filed June 14, 1886.

To aZZ whom it may concern:

Be it known that I, GEORGE A. DEITZ, a citizen of the UnitedStates,residing at Chambersburg, in the county of Franklin, State ofPennsylvania, have invented certain new and useful Improvements inSeal-Locks, of which the following is a specification, reference beinghad therein to the accompanying drawings, in which Figure 1 is a sideelevation of a portion of a car and door provided with my improved lock.Fig. 2 is a vertical section taken on the linear of Fig. 1. Fig. 3 is alike section showing the lock open.

Like letters referto like parts in all the figures of the drawings.

The object of my invention is to provide a receptacle for a manifest orbill of lading, and a seal which shall be punctured, ruptured, ordefaced in the act of unlocking a car-door, in order to provideunmistakable evidence of unauthorized tampering with the lock.

Other objects and advantages will appear in the following description,and the novel features of my invention will be particularlypointedout'in the claims.

A represents a portion of a car-door; and,l3 the door-post, or a portionof the frame-work of the car adjacent to the door.

0 represents a casting secured upon or recessed in the edge of the door,and provided with aprojecting lug, 0, having in its upper face teeth 0G, the front face of the former being slightly inclined and that of thelatter substantially vertical. The casting G is also provided with anaperture, 0, for the wire of an ordinary lead seal.

Secured upon and set within arecess in the post 13 is the lock-case D,the upper portion of which is provided with a receptacle, D, for a billof lading or manifest, which receptacle is closed by a cover, D adaptedtov slide in grooves or flanges Diformed as a part of the receptacle.The cover D and the end wall of the receptacle are each provided withapertures D D, respectively, for the wire of an ordinary lead seal. Therear wall of the receptacle D is slotted, as at D, and over said slots Isecure,by cement or in any other suitable manner, a paper, glass,orother breakable seal, E.

The lock-case D is constructed to form a main receptacle, F, for theoperative parts of the I looking and seal-canceling mechanism. Thesecomprise a pivoted or pendulous locking-bolt, G, and a similarlyconstructed and operating stamp-canceler, H. The locking-bolt isprovided near its front edge with a seal wire aperture, G, and at itslower edge with teeth G G adapted to fit the teeth 0 O of thedoorcasting. It is also provided with a finger-hold, G to facilitatedisengaging the bolt from the door-casting.

A rod or bolt, G", serves as a pivotal bearing for the locking-bolt,said rod being supported in the walls of the case. The upper edge of thelocking-bolt is provided with a curved recess, G in which the lowerweighted end of the canceling-lever rests when the door is locked. Theremaining outline of the up per edge of the bolt is such that when it isturned upwardly on its pivot the cancelinglever is oscillated on itspivot H, so as to th row its upper end, which is made in the form of twoblades, Hflinto the slots D, and through any seal arranged thereover,and within the manifest-receptacle D, as clearly shown in Fig. 3,whereby said seal is mutilated or destroyed, and serves as evidence thatthe belt of the lock has been separated from the doorcasting.

The operation of my invention will be readil y understood from the abovedescription, and it will be noted that all of the operative parts aresecurely contained within the lock case, as well as the fastening-boltsI for the same, the heads of which are covered, while the threaded endsare within the car, so that access to the operative parts or to the sealis impossible without leaving evidence thereof.

Of course it is understood that an ordinary lead seal, as J, will beemployed to retain the locking-bolt in connection with the door-casting,and also the sliding cover over the manifest box or receptacle thereof.

Having described my invention and its operati on, what I claim is-- 1.In a car'door fastening, the combination, with the pendulonsseal-canceling lever H, of the pivoted locking-bolt G, having the curvedrecess G in its upper edge, and having teeth G G in its lower edge, aear-door casting hav- ICO ing teeth conforming to the teeth of thelocking-bolt, and a manifest and seal receptacle the rear'wall of whichis slotted, substantially as specified.

2. The combination of the lock-case D, formed with themanifest-receptacle D, slotted, as at D*, and provided with a cover, Dhaving a sealwire aperture, the pendulous seal-canceler H,thelocking-bolt constructed substantially as described, and the car-doorcasting having the lug 0, provided with the teeth 0 G, substantially asspecified.

3. The combination, with the door A, the

door-casting 0, having the aperture G and lug O, with teeth thereon, thepost B, and easing I 5 D, set therein, and provided with the receptacleD, projecting downwardly into the main receptacle of the casing, andslotted, as described, the pendulous seal-canceling lever H,

having" the blades H and the locking-bolt 20 adapted to swing the leverin its unlocking movement, substantially as specified.
